Question

Rosie is planning to make raspberry lemonade for a party. She needs to add two scoops of raspberry to every 5 cups of lemonade. The data shows the ratios needed. What ratio does the consistent as a proportionality appear?

Answer 1

The proportionality in this case is the ratio of raspberry scoops to cups of lemonade.

From the data, we can see that for every 2 scoops of raspberry, Rosie needs 5 cups of lemonade.

Thus, the consistent proportionality can be written as:

2 scoops of raspberry : 5 cups of lemonade

or

2:5
